Researchers at Moscow’s Mendeleev Russian University of Chemistry and Technology have developed a method of “essentially everlasting data storage” on quartz discs instead of traditional CD ones.
Unlike a CD disc where data is stored on its surface, with the new quartz disc data is stored inside it on a layer-by-layer basis, using what scientists call the nanolattices pattern. That is said to enable users to save up to five bits of data per dot instead of just one as is with conventional storage solutions.
The Moscow researchers say such discs can store as much as a terabyte (1,024GByte) of information—for example, about 500 movies or more than 200,000 archived documents.
In addition to that, the new quartz discs are believed to be exceptionally stable when exposed to such external factors as high pressure and temperature, and electromagnetic fields. They can survive a heavy fire without losing any data, too, the researchers claim.
The Mendeleev University team has been working on this project to order from Russia’s Advanced Research Fund (ARF), the national analog of the U.S.’ DARPA.
